It may be well at the ouisret is briefly lescriliur a typical fabric that a machine en hedying the invention is adapted to produce automatically and eoniinuziu'sly. and for this purpose the towel of he Clewie Patent X0. 752.033 above mentioned is selected. This fail-iris comprises a series of io giiudinnlly extending chain warp threads and a eries of longitudinally extending filling warp threads which also extend tramvemely to knit logei'her mijarenb chain warp mrezuls.

The chain warp threads may he v.xzneiilered as composed of sets of four threads each, (he flu-ends m the, eevernl sen; being lettered u, I), 1'. u', mul a. 1:, (1', etc. The fiiling warp tlu-emk may he emisidereri 21% compused of eels of three threads eueh, the threads of the several sets being lettered e, f, g. and c, f, 5;, etc. Starring on the lefthand side of Fig. In the reciprocm tion of the needles. the thread 3 is carried back aml forth het n en fimi knitted to threads (1 and 71, the ilnemi rried back 2111! forth between :uhi knitted. :0 threads 1) aunl 1a and the thro-ui g is carried back and forih between and knitted to threads I: and (I.

After a definite length of the felzric so l mit, the t'hreml r is carried from thread a, through loops formed by three 5 and n, in thread d. to which it is imiiierl the ilareaai 1 being then returned to thread a in a. simihu' manner and then hack to thread :1.

and b, and the thread a between threads a and d. There is thus formed a strip of closed fabric J. The thread e is then carried back and forth between threads I! and o, the thread heel? and forth between a and a, the thread 9 back and forth between I) and a, the thread e back and forth between d and 0', etc. Thus there are formed a series of closed blocks K, K, etc., separated by spaces L, L, etc. The thread 6 is then carried back and forth between threads 1 thread 9 between threads 6 and a, thread 6 between threads at and (1, etc. There is thus formed a closed strip M similar to strip This completes a description of one repeat of the body of the fabric.

In knitting the fringe, the filling warp threads are passes back and forth in the same manner as during the formation of closed blocks H or K, but for a substantially greater number of reciprocations of the needles than in the formation of said blocks, each section 0 of fringe so formed ing several times the length of one of the blocks H. In knitting the fringe, the tension on the filling warp beam, is increased, so as to draw the threads a, b, c and d, or (as shown) 0, d, '1" and b, of a set relatively close together, whereby the fringe is more closely knitted than the bioclis H or K, while the spaces P between fringe sections are substantially wider than spaces I or L.

It will be noticed from the foregoing description that at any given pom: in the length of the fabric the filling warp guide bar is shifted to carry each filling warp thread either from one chain warp to the nextadjacent chain warp or from one chain warp to the third adjacent chain warp, and it will be understood that, to knit the body of the fabric, the proper sequence of movenients can readily be imparted to the filiing warp guide bars from a single pattern wheel or chain of reasonable length. VVh'en, however, the fringe is being imit, the filling threads must be carried back and forth between adjacent chain warps for a comparatively large number of successive needle reciprocations, this involving, the actuation of the filling warp guide bar by difi'crent pattern mechanism or difi'crently actuated pattern mechanism. In the embodiment of my invention herein described this is effected by automatically shifting the guidc-bar-operab ing bell-cranks carrying the rollers engaging the pattern mechanism from one pat tern chain to another. said shift being controlled by other pattern mechanism. which aiso controls the operation of means for varying the tension imposed upon the filling warp beam.

The machine embodying the invention! will now be described. f;

10 is the chain-warp guide-bar carrying l l 1 i I I the guides 11 for the threads a, Z 1, d, a, b, c, d, etc. I

510 is the iiiling-warp guide-bar carrying the guides 21 for the threads 0, f, g, e, f g, etc.

30 is the needle bar carrying the needles 31. a

40 is a shaft having hearings in the machine frame 9. From the shaft 40 are suspended holders 41 through which loosely extend respectively rods -42 secured to the respective guide bars 10 and 20. This permits each guide-bar to be moved, in the direction of its length, relatively to its corresponding holder.

Connected with the guide bars respecti ciy are links 1:! and 22 respectively cured to hell-crank levers 13 and J3 pivoted on a shaft 49. The bell-crank levers l3 and E23 carry rollers 1% and '24 respectively cugaging respcctivclv pattern chains 15 and 25 carried respectively by wheels 16 and 26 on the pattern shaft 50. The shaft also carries a third wheel 27 carrying a third pattern chain 28.

On the shaft 50 is a sprocket wheel 51. Connecting sprocket wheel 51 and a s rocket wheel on a stud 53 is a sprockrt c ain 54 carrying a pin or pins 55 adapted to intermittently en age a star wheel 56 on a shaft 57. Secureu to the shaft 57 is a sprocket wheel 58 which is connected bya sprocket chain 59 with a sprocket a heel 60 on a shaft 61. On the shaft 61 is a sprocket wheel 62 which is connected with a sprocket wheel 63 b 21 sprocket chain 64 carrying iugs 640. livoted to the machine frame is a lever 65 in line of travel of the lugs (340.

68 is a link connecting the lever 65 and one arm of a bell-crank lever 5?, which is pivoted on the machine frame. The other arm of bell-crank (37 carries pins 68 engaging a groove in the extended hub of the bell-crank lever V I 70 is the shaft for operating the needlebar 30. 011 the she 5t 70 are the cam 76 actuating levers 77 pivoted on the machine frame. Connected with levers 77 are rods 78 depending from the needle bar 30. By this mechanism the needle bar is reciprocated vertically. On the shaft- 70 is a bevel pinion 71 engaging a bevel inion 72 on a counter shaft 73. The sha 73 carries a bevel pinion 74, which engages and actuatcs a bevel wheel 75 on the shat t 50.

The operation of the mechanism just described is as follows: The shaft 70 drives the shaft 50, and the pattern chains 15 and 15 actuated thereby engage respectively the roliers l4.- and 2-} on the bell-cranks 13 and 23, thereby actuating the guide-bars 10 and 0 in such a way as to dictate the formation of the body of the fabric as hereinbefore dcscribed. To particuiariz: "lhe attcrn chain 25 is of such length and provi ed with projections of such height that the bell-crank 23 will be actuated to so shift the guide-bar 20 as to dictate the formation of one repeat of the body of the fabric. The number of repeats that will be formed before the knit" ting of the fringe will be dictated depends upon the length of chain 54, the number of pins on chain 54. and the distance between the pins 640 on chain (5-1. These factors can be varied to dictate the knitting of any desired length of fabric. After such length of fabric has been knitted, one of the pins 540 engages and depresses the lever 65, which, through the link 66 and bell-crank (l7 shifts the bell-crank .23 out of engagement with pattern chain 25 into engagement with pattern chain 28. The pattern chain 28 is of such length and is provided with projections of such height that the bell-crank 3.3 will be actuated thereby to so shiftthe guide-bar 20 as to dictate the formation of the fringe O of the fabric. After the fringe is knitted to the desired length, the pattern mechanism is so timed that the pin 640 passes beyond the lever 65, whereupon the bell-crank 23 is returned into position to rcengugc the pattern chain 25, whereupon the knitting of the body of the fabric is resumed. The bellcrank 23 is so returned by means of a weight or weights 80 connected, by means of a cord 81 extending over rollers 82 and 83, with the lever 65.

90 is the filling warp-beam'and 91 its axle. Secured atone end to the machine frame and extending around the hub of the warpbeam Wis a strap 92, which is connected at: its other end to a slotted link 93, whose slot engages a pin on one end of a lever 94, pivoted between its ends on the machine frame. From the slotted link 93 is suspended a weight; or weights 95. T be other end of the lever 94 is secured to the cord 81.

Itwill be understood that during the knitting of the body of the fabric the weight 80,

which is substantially heavier than the weight 95, not only holds the bell-crank lever 23 into engagement with the patternchain .25, but also lifts the weight 95 so as to relieve the tension on the warp-beam. -When, however, the lever 65 is depressed to cause the bell-crank lever 23 to be shifted into engagement with the pattern chain 28 to dielate the knitting of the fringe, the weight is lifted and the lever 94 is rocked, allowing the weight 95 to impose a. tension upon the brake-strap 92. The tension of brake-strap 92 may be regulated by varying the weight 95 to a maximum less than weight 80. The greater the tension imposed upon the filling warp-beam 90, the closer together the chain warp threads a, b, e, d, etc., will be drawn by the increased tension applied to the filh ing war threads e, f, g, etc.

It wil be understood that, by means of independent weights (not shown), a tension may be applied to the filling warp-beam appropriate to the formation of the body of the fabric, the device herein described bring eliective to increase the tension during the knitting of the fringe only.
